Experiment No. 1Aim:-Write a C-Program to take the radius of sphere as input and print the volume and surface area of that sphere.

/* Program for finding volume and surface area */

#include<stdio.h>

#include<conio.h>

#define pi 3.14

int main()

{

float r,vol,area;

printf("enter the radius\n");

scanf("%f",&r);

vol= (4.0/3)*pi*r*r*r;

area=4*3.14*r*r;

printf("volume of sphere=%f\n\n\n",vol);

printf("surface area=%f",area);

getch();

}

/* Output */
